The ugly side of Ashes cricket came to the surface on Boxing Day when David Warner was involved in yet another spat with England fielders.
Warner appeared to mouth abuse at Jonny Bairstow after Tom Curran, on his debut, had provoked the Australian with verbals of his own. Bairstow and other senior England players then joined Curran, helping out the youngster as he battled it out with one of cricket's most aggressive players.
At one stage it looked as though James Anderson was asking umpire Sundaram Ravi whether he had heard what Warner said as the official stepped in to calm down fraying tempers.
Sledging was a recurrent theme of the first two tests, particularly in Brisbane as both sides looked to take the initiative in the series. Warner upset England at the Gabba and there were more flashpoints in Adelaide.
But in Perth both sides were much calmer and even though it was denied officially, it looked as if match referee, Richie Richardson, had told the players to behave better or he would start to take action. Richardson has left, to be replaced by Ranjan Madugalle, the ICC's most senior match referee, for the Melbourne-Sydney leg of the series.
